Is Anki good for language learning?

Anki is excellent for memorising items you have already decided to learn — vocabulary, characters, facts. It is not designed to train sentence production, so it does not close the gap between recognising a word and saying it.

Do I need to make my own Anki cards?

Shared decks save time but produce cards you did not choose. Making cards from your own reading is slower and generally more useful, because the card carries the context you met the word in.

Fluency Gym vs Anki: Which Builds Speaking Fluency Faster?

Updated 2026-11-03 · Ellen Zhang Yarong

Short answer: if you want to remember 2,000 words, Anki is the better tool and it is free. If you want to produce sentences out loud without translating, Anki is the wrong instrument — not because it is bad, but because it is not built for that.

What Anki actually is

Anki is a spaced-repetition scheduler wrapped around user-made cards. Its core loop is: see a prompt, try to recall, reveal, grade yourself, and let the algorithm decide when you see it again. It is free on desktop and Android, open source, and handles thousands of cards without complaint.

The scheduling is the part that matters. Spacing review across days produces substantially better long-term retention than massing it into one session; that effect is well established across hundreds of experiments (Cepeda et al., 2006).

Where it stops

Anki trains recall of the thing on the card. If the card says perro → dog, you are training translation in one direction. If it says dog → perro, you are training word retrieval. Neither trains the thing a conversation demands, which is producing a whole sentence, with the right form, under time pressure.

That gap is not small. Retrieval practice studies show retention collapsing when items are dropped from testing once "known" (Karpicke & Roediger, 2008), which is exactly what a well-tuned Anki deck does: it stops showing you what you reliably answer.

Where a sentence-level trainer differs

| | Anki | Sentence-level trainer | |---|---|---| | Unit of practice | card (word or fact) | sentence | | Input | your own cards or shared decks | any text you paste, parsed to CEFR level | | What it trains | recognition and cued recall | production from a cue | | Time to first session | depends on deck building | minutes | | Price | free (iOS paid) | see pricing |

When Anki is the better choice

You are memorising high-volume, low-context material: characters, medical terms, capital cities.
You already have a deck you trust and a review habit.
You want complete control over scheduling parameters.

When to switch

You can pass your Anki reviews and still cannot say a sentence about your own day. That is the signal: the deck is doing its job, and the job is not the one you need.

A sentence-level recall trainer is not a flashcard app. Try a workout.

What to migrate from Anki (and what to leave)

Bring the vocabulary you keep failing — the leeches, the cards you have reset three times. Those are exactly the items that need sentence-level practice rather than another interval change.

Leave the bulk deck. Four thousand recognition cards that you answer correctly are not the problem, and migrating them would cost a week and teach nothing.

A workable split: keep Anki for high-volume recognition, and take only your failed items into production practice. Your review time drops, your speaking does not.

A realistic example of using both

Suppose your deck contains aunque and you recognise it immediately, but you never use it while speaking. Keep the card if the word still matters to you. Add a separate production prompt based on a situation you might actually describe: “Although it was raining, I went out.” Try saying the equivalent sentence in your target language before looking at your model answer.

The card and the sentence prompt have different jobs. The card checks whether you can retrieve a meaning from a compact cue. The sentence checks whether you can retrieve a connector, choose a clause structure, and finish a thought. If you miss the word, return it to the vocabulary deck; if you know the word but cannot build the sentence, practise the sentence frame. That diagnosis keeps you from endlessly changing Anki intervals for a problem the scheduler cannot solve.

A practical weekly review can stay modest: flag the few cards that repeatedly fail, choose one or two to turn into personal sentences, and leave the rest of the mature deck alone. Do not export and rebuild thousands of cards because speaking feels slow. The collection may be doing its intended job; it simply measures a different outcome. You can compare progress by recording the same kind of short explanation periodically and noticing whether you can now express ideas that used to force a pause.

There is no need to choose a single app for every language-learning task. Keep the tool that reliably helps you remember individual items, and add an output exercise only where you have a clear production gap.
